2.4.2 Mixer
Function of the Mixer
Mixer M9 is located after System pump A and System pump B, and before the Injection valve. The
Mixer is a dynamic mixer for high-performance gradients. It is used to make sure that the buffers from
the System pumps are mixed to give a homogenous buffer composition.
The Mixer has a built-in filter that prevents particles from reaching the column.
Replace the sealing ring of the mixer with a highly resistant O-ring if the system is going to be
exposed to organic solvents or high concentrations of organic acids for longer periods of time.
Refer to Section 7.8.4 Replace the O-ring inside the Mixer, on page 323 for how to change the
ring.
